param type varies passed by reference (required)
The meaning of param depends on the controlcode
being used. However, no matter what the controlcode
is, a value must always be assigned to param.
NOTE For a number of the controlcode functions param has no meaning. In
those cases it must be coded as a dummy parameter, with a value of 0,
because it is a required parameter.
The following pages describe each controlcode value. Each description
includes the use of param, the meaning of condition codes, and any
special considerations or additional discussion.
